Interface LongToDoubleFunction

All Superinterfaces:

Function<Long,Double>, Function<Long,Double>, LongFunction<Double>, LongFunction<Double>, LongToDoubleFunction, ToDoubleFunction<Long>, ToDoubleFunction<Long>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface LongToDoubleFunction
extends LongFunction<Double>, ToDoubleFunction<Long>, LongToDoubleFunction

Represents a function that accepts a long-valued argument and produces a double-valued result. This is the long-to-double primitive specialization for Function.

This is a functional interface whose functional method is applyAsDouble(long).
